OPH'ILHALM I G MOUNT ING Filed Sept. 29, 1934 SAMUEL 'E. BOUCHARD INVENTOR ATTORNEY Patented May 18, 1937 UNITED STATES PATENT OFFIC OPHTHALMIC MOUNTING Application September 29, 1934, Serial No. 746,231

Claims.

The present invention relates to ophthalmic mountings and more particularly has reference to mountings for rocking nosepads.

One of the objects of the present invention is 5 to provide an improved mounting for rocking nosepads. A further object of the present invention is to provide a rocking nosepad mounting which is simple to manufacture and assemble and yet rugged and durable. These and other objects and advantages reside in certain novel features of construction, arrangement and combination of parts as will hereinafter be more fully disclosed and pointed out in the appended claims.

Referring to the drawing:

Fig. 1 is an elevation of a pair of spectacles embodying my invention.

Fig. 2 is a detail view of the face of the supporting arm.

Fig. 3 is a detail view of the edge of the supporting arm.

Fig. 4 is a rear elevation of one form of nosepad.

Fig. 5 is a side elevation of the nosepad shown 25 in Fig. 4.

Fig. 6 is a side elevation of a modified form of nosepad.

Fig. 7 is a rear elevation of a further modified form of nosepad.

Fig. 8 is a side elevation of the nosepad shown in Fi 7.

A preferred embodiment of my invention is shown in the drawing wherein 10 indicates a bridge fastened at each end to a rim II holding 35 a lens 12. A non-metallic nosepad I3 is also fastened to each rim l l by means of a metallic supporting arm I4 which is provided with an aperture [5 near its free end. Each nosepad [3 has a metallic insert l6 which extends from the rear 40 face of the nosepad to form a tube H for loosely receiving the supporting arm M to permit a rocking movement. The outer portion. of the tube I1 is provided with a tang l8 which is bent inwardly into the aperture of the arm [4 when 45 the nosepad I3 is mounted on the arm thus forming a durable and rugged connection.

In the modification shown in Fig. 6, the metal-- lic insert I9 is wholly within the nosepad l3 while a tubular metallic member is fastened 50 to the metallic insert l9 and extends from the rear face of the nosepad. The connection to the arm I4 is the same, a tang 2| on the rear face of the tube 20 extending into the aperture 15. In this modification, the metallic tube 20 com- 55 pletely surrounds the metallic arm l4 and the wear due to the rocking movement is less than in the embodiment shown in Fig. 5 where the metallic arm l4 bears against the non-metallic nosepad l3.

Figs. 7 and 8 show a modification wherein the arm 22 extends horizontally and terminates in a downward bend to engage the horizontal tube 23. The connection between the arm and the nosepad is by means of an inwardly bent tang 24 as in the previously described embodiments and the tube may be of either of the forms shown.

While I have illustrated my invention in connection with an ophthalmic mounting having rims surrounding the lenses, quite obviously my invention is as well adapted for use with rimless mountings and in such a case the arms l4 would be fastened either directly to the bridge or to the lens holding members. It is also obvious that instead of apertures [5, the arms 14 could be formed with depressions for receiving the tangs. Various other modifications can obviously be made without departing from the spirit of my invention.

I claim:

1. In an ophthalmic mounting an elongated connecting member having an aperture at its outer end, a nosepiece, a tubular member extending fro-m said nosepiece for loosely receiving said connectingmember, and a tang on said tubular member for engaging the aperture in said con necting member.

2. In an ophthalmic mounting, an elongated support apertured near its end, a nosepiece, a tubular member extending from the rear face of said nosepiece for loosely receiving said support and means on said member extending into said aperture to prevent withdrawal of said support from said member.

3. In an ophthalmic mounting a supporting member having an aperture near its end, a nose engaging member, a tube extending from the rear face of said nose engaging member for loosely receiving said supporting member, and an inwardly bent portion on said tube for loosely engaging said aperture.

4. In an ophthalmic mounting a nose pad, a metallic tube extending from the rear face of said pad, the axis of said tube being substantially parallel to the plane of said pad, and a tang formed in a wall of said tube and adapted to be bent inwardly into said tube.

5. In an ophthalmic mounting, a nose pad and a metallic tube extending from the rear surface of said pad, said tube having a U-shaped cut in one wall thereof to form an inwardly bendable tang.

SAMUEL E. BOUCHARD.
